Question

Think about the function f(x) = 10 - x
What is the output, or dependent variable?

Answer 1

Answer:x

Step-by-step explanation:x is the input, or independent variable and f(x) is the output, or dependent variable or quantity. f(2) represents the output (y-value) when x = 2. The value of f(2) is 2.

Answer 2

The dependent or output variable is f

Explanation:

The given function is

`f(x) = 10 - x`

We want to to determine, the output or dependent variable.

Recall that we can rewrite this function as:

`y = 10 - x`

Here we can clearly see that y is the output or dependent variable.

But do you know

`y = 10 - x \: means \: y(x) = 10 - x \: {?}`

This tells us that y is a function of x.

Similarly,

`f(x) = 10 - x`

means f is a function of x.

Therefore the output variable is f.
